Swell Summary

Outlook through Saturday January 27: Surf will remain elevated along east facing shores through Sunday, before dropping below the advisory level of 8 ft early in the week. A small northwest swell is expected to arrive tonight, and then be reinforced with a long-period, moderate west-northwest swell Sunday night. This swell will peak Monday night near advisory level, then gradually lower through midweek. A small background swell from the south will persist through the forecast period.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
